| \chapter{Building HelenOS} |
| \section{First time} |
| HelenOS features a user friendly configuration system. |
| \section{Requirements} |
| To build HelenOS, the following build tools must be installed: |
| \begin{itemize} |
| \item GCC 4.1.1 + binutils 2.16.1 cross compiler environment for target platform |
| \item python 2.3 or higher |
| \item GNU make |
| \item mkisofs |
| \end{itemize} |
| The GNU build environment is best downloaded, compiled and installed |
| automatically using the shell scripts located in the |
| {\em kernel/contrib/toolchain} directory. |
| |
| \section{Building} |
| HelenOS features a user friendly configuration system. Once |
| a {\em make} command is run from the {\em boot/} directory, a |
| {\em dialog} driven application is started and the developer is asked several |
| questions regarding build configuration parameters. The answers are saved |
| in the file {\em Makefile.config} in the boot/, kernel/ and uspace/ |
| directories and are automatically used for each subsequent build. |
| |
| To change the parameters, the user should change to the particular subsystem |
| directory and type {\em make config}. When the build configuration parameter |
| are changed, the whole subsystem should be completely rebuilt. The |
| configuration system offers user to do this automatically. |
